I don't want answers. I just need help and I need someone to explain it to me ;~; -
I would help you, but math just isn't my beef! I'm sorry. ;~;
-
It's fine..
-
No one? ;~;

Wait...I know how to do some of them.
For the first two, do the equations (4*10-2, etc.) Then convert the number the a decimal.
In nine, you have to distribute first.
I wish I could help more. That's all I have. -
Ik how to do #9!!! :O
-
Oh okay...But wait...If it dosent say what x is how do I do the problem? Do I make up one? Oh I'm stupid...Forget it..
-
Eleven is distributive property.
-
In nine you have to do distribution like Wolf said
then you need to combine like terms
and then you add or subtract depending on their integers -
Give me a sec, Zane.
-
What grade are you in???
-
But whats x ? Is it just a random part of the equation...?
Okay Vege..
10th.. -
This is sad,but I'm 20 and can't do this s---.How did I pass? No f---ing clue...
